GRAIN-CLEANERS.

Specili'caiion forming part of Letters Patent No. 211,609, dated February 1G, 1864.

To all whom, t may concern:

Be it known that I, WILLIAM S. DErsHER, of Hamburg, in the county of Berks and State of Pennsylvania, have inventedanew and Improved Grain Gleanin'g and Separating Ma-A chine; and I do hereby declare that the fol lowing is a full, clear, and exact description of the same, reference being had'to the accompanying drawings, making a part of this speciiication, in which- Figure l is a vertical central section of my invention, taken in the line x Fig. 2; Fig. 2, a horizontal section of the same, taken in the liney y, Fig. l; Fig. 3, a vertical section of a portion of the same, taken in theline e z, Fig. 2.. p

Similar' letters of reference indicate corresponding parts in the several figures.

rlhis invention consists in a novel and iinproved grain-separating device and fan attachment, whereby it is believed that several advantages are obtained over the ordinary means employed for that purrpose.

To enable those skilled in the art to fully understand and construct my invention,I will proceed to describe it.

A represents a framing, which may be constructed in any proper manner to support the working parts of the device, and B is a bedstone which is fitted on the upper part of the framing A, and C the top stone or runner which rests on and is driven by a spindle, D, the latter being stepped in the lower part of the framing A.

E is the curb which encompasses the stones B G, and F is a suction-blast spout of inverted-U form, which extends over the curb E at some distance above it, and down at its sides at two opposite point-s, one side, f, of the blastspout being longer than the other side, f', as -shown in Fig. l. The longer side, f, of the spout F is of oval form in its transverse section, and said side has an opening, g, made in it, through which the grain from the stones passes, an opening, h, being made in the curb E for the grain to escape from the stones. At the lower edge of the opening g there are a series of 'vertical teeth, t', which serve as scatterers to spread the grain as it falls into the side f of the blast-spout, (see Fig. 3,) and causes the said grain to be acted upon in a more eficient manner by the blast,as the grain will fall in a thin sheet or stream, and all the impurities be subjected to the action of the blast. In the upper horizontal part of the blast-spout F (designated by f there are two valves or slides, G G', of angle or V forni. These valves or slides are attached to rods H H, which pass up through the horizontal part f of the blast-spout, and have screw-threads cut on them, on which nuts j are fitted for raising and lowering the valves or slides, as willbe understood by yreferring to Fig. 2.

The part f of the blast-spout has two penden t tubes, I I', attached to it, one near each end. These tubes are just below the valves or slides G G', and each tube has a self-acting or loaded valve, J, at its lower end.

To the lower end of the shorter side f of the blast-spout F the fan-box K is Iattached, having two eduction-passages, k k,between which a valve, L,is placed. This valveL is of curved or segment form, and it has an arm, t, attached to it,which passes through aslot, m, in the side of the fan-box for the purpose of allowing the valve to be moved or adjusted to the right or left to close either passage k or k.

The dress ofthe stones previously described admits of the runner being rotated in either direction, and the valve L, in consequence of being arranged relatively with the eductionpassages k 7c', as shown, admits of the fan M being rotated in either direction, as the of'al may be discharged through either of the eduction-passages. The valve L also serves asa register to regulate the blast of air through the spout F. When from any cause the blast of air is too strong, it may be reduced by simply moving the valve so that it will partially diminish the area of the discharge-orifice.

The blast generated by the fau M draws up all the light impurities from the descending grain in the side f of the blast-spout. The light and imperfect grain will fall into the tube I, it being too heavy to be carried farther by the suction-blast, while the lighter impurities-such as cockle, chess, &c.*will fall into tube I, the dust and lighter impurities being drawn into and discharged from the fan-box K by the action of the fan M.

By adjusting the valves or slides G Ghigher or lower, the discharge of thelight grain and coekle or chess into the tubesll may be regulated and the separation ofjsaidparts graduated, as required.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The employment of the scattering-teeth i a' i t' Within the blast-spout and at the edge of the eurb-opening g, in the manner and for the purpose herein shown and described. Y

2. rIhe employment of the adjustable angular guiding-slides G, When arranged to operate in conjunction with the blast-spout F and controlled, as set forth. 1
